Parts are tested in the circuit of the Typical Operating Circuit. Symbol Parameter Min Typ Max Unit Test Conditions Note 1: Input voltages may exceed the supply voltages provided the input current is limited to ±100 µA. 2: Dissipation rating assumes device is mounted with all leads soldered to printed circuit board. 3: Refer to “Differential Input” discussion. 4: Backplane drive is in phase with segment drive for “OFF” segment, 180° out of phase for “ON” segment. Frequency is 20 times conversion rate. Average DC component is less than 50mV. 5: The TC7116/TC7116A logic inputs have an internal pull-down resistor connected from HLDR, Pin 1 to TEST, Pin 37. The TC7117/TC7117A logic inputs have an internal pull-down resistor connected from HLDR, Pin 1 to GND, Pin 21. |
